Kai's verdictA-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for model-shopping. I use this for every prototype before committing.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.
